Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera device.

[0002]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the handleability of conventional cameras and to develop various removable, specifically variable, devices.

[0003]

The above objects are achieved by the present invention. A camera device of the present invention includes a basic element and a photographing housing, the basic element has a through opening arranged on an optical axis, and a first housing for accommodating a lens is provided in front of the through opening. Is provided, and on the rear side there is a second attachment point for fixing the shooting housing.
Further, the basic element has at least a main adjustment module for adjusting the shutter speed, and a third mounting portion for mounting the handle portion, which is orthogonal to the optical axis. It is rotatable about a position and can be fixed at two opposing positions and a third position rotated 90 degrees with respect to these positions, and the photographing housing is centered on the optical axis at the second mounting position. It is characterized in that it can be arranged at two positions rotated by 90 degrees, specifically, it can be rotated.

In the camera device of the present invention, for example, the photographing housing constitutes a part of the finder camera, and is provided with a replaceable finder, for example, a frame finder in some cases. Alternatively, the imaging housing forms part of a single-lens reflex camera and is provided on the front side of the mirror box, and the mirror box is provided on its upper side with a possibly interchangeable viewfinder, for example, a prism viewfinder. The photography housing may be coupled to the second mounting point of the basic element via various adapters, for example bellows adapters.

Therefore, the camera device according to the present invention always provides good operability for both right-handed and left-handed users, as well as in landscape photography and portrait photography. There is no need to change hands when changing from portrait to landscape. All operating elements are located at the user's hand. Moreover, this is the same whether the operation is performed with the right hand or the left hand.

The first mounting point is preferably a bayonet, about which the basic element is rotatable, so that additional joint points are omitted. Therefore, there is no tolerance arising from the joint. Since the adjusting and operating elements are completely separated from the shooting housing, it is easy to replace the SLR camera with a viewfinder system camera or a TLR camera while using the same basic elements. Furthermore,
It is possible to change to a camera having front plate movement and tilt functions without using a special lens.

The choice of lens can be made from a purely optical point of view. In terms of optical design, there is no need to compromise because of the mirror box. The luminosity of the image in the finder does not inevitably depend on the brightness of the lens, in particular on the filter. In terms of the finder camera function, the auto focus and the range finder can be easily driven.

The camera device has various rear parts, for example, a handy back wall for KB film or APS film, a motorized back wall for KB film or APS film, a handy replacement cassette for KB film or APS film, KB film. Alternatively, a motorized exchange cassette for APS film, a Polaroid magazine or a digital rear can be used.

In the case of a finder camera system, it is also possible to use a lens that passes through the through-opening of the basic element and reaches the film surface directly. The viewfinder can also be replaced if it fits the interchangeable lens. Various shutter types are also selected.

When a bellows adapter is attached to the camera device, for example, the basic element is rotated so that the third attachment point is located substantially vertically. The third mounting point is a mounting point for a tripod. In this structure, the handle portion and the main adjustment module can be a remote control member that can be separated from the basic element.

In order to improve the handleability, the handle portion and the main adjustment module can be rotated about the axis orthogonal to the optical axis at the third attachment point, and can be fixed at any rotation position.

The photographing housing 2 can be arranged at two positions, which are rotated by 90 degrees about the optical axis 7 at the second attachment point 10, and more specifically, can be rotated. One of two positions is shown in FIG. In this position, the film gate 13 is horizontally oriented. In FIG. 2, the photographing housing 2 is rotated 90 degrees with respect to FIG. 1 and is placed vertically. The photographing housing 2 attached to the second attachment point 10 is preferably fixed in two final positions shown in FIGS. 1 and 2 by a rotation fixing member (not shown).

The main adjusting module 5 has adjusting means for shutter speed and other operating elements, while the handle 6 contains another operating element 14 and a housing (not shown) for housing at least one battery. ) And have.

In order to change the camera device for left-handed use, the basic element 1 is moved from the position shown in FIG. 1 to the position shown in FIG.
Rotate 0 degrees. In the position shown in FIG. 4, the main adjustment module 5 and the handle portion 6 are reattached to the third mounting point 11
Attached to.

The camera device shown in FIGS. 3 and 4 is a single-lens reflex camera. A detachable mirror box 1 on the front side of the shooting housing 2 of the single-lens reflex camera
5 are provided. A detachable prism finder 16 is provided above the mirror box 15. Basic element 1
The handle portion 6 is in the right-handed position in FIG. 3,
In FIG. 4, it is in a left-handed position rotated by 180 degrees.

In the embodiment shown in FIG. 5, the photographic housing 2 is connected to the second mounting point 10 of the basic element 1 via a bellows adapter 17. At this time, the basic element 1 is rotated 90 degrees downward with respect to the position of FIG.
